5) your Power supply will have ampere rating for your 12vDC Power Supply written on the Label on it... your CPU/MB/GPU will use this Voltage and Current... This is why they make different Wattage Power Supplys... it's for more 12vDC current from them.
your GPU requires 106 watts
your CPU requires 73 watts
so you need a minimum of 12vDC@ 15 amperes for those two components.
